In case ping is sent to own address, the request is looped back to the
stack and served before ping work had a chance to reschedule. In result,
when the final ping reply has been server, and ping operation finalized
with `ping_done()`, the work was rescheduled one last time, causing the
ping timeout to be reported. Fix this by rescheduling the work before
sending the actual request, so that the reply handler can cancel the
work properly in such case.

Fix two issues with net tcp command:
* The `net tcp` commands are still based on net_context API. For TCP,
the API caller (net shell) should add one extra reference to the
allocated net context, to prevent premature context release in case of
connection teardown. Currently that was not the case, and the context
was released too early, resulting in missing final ACK from the Zephyr
side on connection close.
* The net context API should not be called from the registered connect
callback, as this creates a temporary deadlock situation. The
net_context_connect() function blocks until the connection is
established, or an error or timeout occurs. For that time the
net_context mutex is being locked. In case of connection error (for
example after receiving RST packet) the connect callback is called,
indicating an error. If we try to call net_context API from within, a
deadlock situation takes place, as the context mutex is still locked
by the net_context_connect() (called from the shell thread). This
blocks the further execution of the TCP stack and can result in an
unexpected behavior (like for example retransmitting the SYN packet,
which takes place from yet another thread, TCP work queue).
Fix this, by releasing the net context not from the callback directly,
but based on the return value from net_context_connect().

Replaces the previous approach to define bands via hardware capabilities
by the standard conforming concept of channel pages.
In the short term this allows us to correctly calculate the PHY specific
symbol rate and several parameters that directly depend from the symbol
rate and were previously not being correctly calculated for some of the
drivers whose channel pages could not be represented previously:
* We now support sub-nanosecond precision symbol rates for UWB. Rounding
errors are being minimized by switching from a divide-then-multiply
approach to a multiply-then-divide approach.
* UWB HRP: symbol rate depends on channel page specific preamble symbol
rate which again requires the pulse repetition value to be known
* Several MAC timings are being corrected based on the now correctly
calculated symbol rates, namely aTurnaroundTime, aUnitBackoffPeriod,
aBaseSuperframeDuration.
In the long term, this change unlocks such highly promising functional
areas as UWB ranging and SUN-PHY channel hopping in the SubG area (plus
of course any other PHY specific feature).

a socket using setsockopt(). With this option, it is possible to bind
multiple sockets to the same local IP address / port combination, when
one of the IP address is unspecified (ANY_ADDR).
The implementation strictly follows the BSD implementation and tries to
follow the Linux implementation as close as possible. However, there is
one limitation: for client sockets, the Linux implementation of
SO_REUSEADDR behaves exactly like the one for SO_REUSEPORT and enables
multiple sockets to have exactly the same specific IP address / port
combination. This behavior is not possible with this implementation, as
there is no trivial way to identify a socket to be a client socket
during the bind() call. For this behavior, one has to use the
SO_REUSEPORT option in Zephyr.
There is also a new Kconfig to control this feature similar to other
socket options: CONFIG_NET_CONTEXT_REUSEADDR. This option is enabled by
default if TCP or UDP are enabled. However, it can still be disabled
explicitly.

There was a corner case which was not handled well in a scenario, when
listening socket was closed during an active handshake with a new
client.
When a listening socket is closed, the accept callback is cleared on the
TCP context. If this happened during a handshake with a new client, i.
e. before final ACK from the client was processed, this lead to a
context leak, as application did not take ownership of the connection
(i. e. had no means to close it).
Fix this, by proactively closing the connection at the TCP level when no
accept_cb is available. Instead of ignoring the fact that no accept_cb
is available, the TCP stack will now enter TCP_FIN_WAIT_1 state and
proceed with a graceful teardown of the connection.

Previously, if a net_context had multiple packets already in
the receive queue, and a call to zsock_recvfrom() was made with
a buffer large enough to receive content from multiple packets,
only the content from a single receive buffer would be received.
Since zsock_recvfrom() is a system call, which has a
non-negligible overhead, it makes sense to receive as many bytes
as possible per system call.
Add zsock_recv_stream_immediate() as a shorthand for
"fill this receive buffer with as many bytes as possible without
blocking". Allow nullable buffer parameters so that we can also
have a shorthand for "count how many bytes are immediately
available".

The IEEE 802.15.4 API and networking subsystem were using several
inconsistent timestamp resolutions and types. This change defines all
timestamps with nanosecond resolution and reduces the number of
available types to represent timestamps to two:
* `struct net_ptp_time` for PTP timestamps
* `net_time_t` for all other high resolution timestamps
All timestamps (including PTP timestamps) are now referred to a
"virtual" local network subsystem clock source based on the well-defined
types above. It is the responsibility of network subsystem L2/driver
implementations (notably Ethernet and IEEE 802.15.4 L2 stacks) to ensure
consistency of all timestamps and radio timer values exposed by the
driver API to such a network subsystem uptime reference clock
independent of internal implementation details.
The "virtual" network clock source may be implemented based on arbitrary
hardware peripherals (e.g. a coarse low power RTC counter during sleep
time plus a high resolution/high precision radio timer while receiving
or sending). Such implementation details must be hidden from API
clients, as if the driver used a single high resolution clock source
instead.
For IEEE 802.15.4, whenever timestamps refer to packet send or receive
times, they are measured when the end of the IEEE 802.15.4 SFD (message
timestamp point) is present at the local antenna (reference plane).
Due to its limited range of ~290 years, net_time_t timestamps (and
therefore net_pkt timestamps and times) must not be used to represent
absolute points in time referred to an external epoch independent of
system uptime (e.g. UTC, TAI, PTP, NTP, ...).

Some DHCPv4 servers do not respect BROADCAST flag set on DHCP Discover,
replying with unicast packet, making it impossible to obtain DHCP
address by Zephyr in such cases.
RFC1542 chapter 3.1.1 makes the following statement about the BROADCAST
flag:
This addition to the protocol is a workaround for old host
implementations. Such implementations SHOULD be modified so
that they may receive unicast BOOTREPLY messages, thus making
use of this workaround unnecessary. In general, the use of
this mechanism is discouraged.
Making it clear that being able to process unicast replies from the DHCP
server is not only an optional behavior, but a recommended solution.
Therefore, introduce a support for unicast DHCPv4 in Zephyr. To achieve
this, add additional filtering rule at the IPv4 level - in case DHCPv4
is enabled, there is an active query and the packet is destined for the
DHCPv4 module, let it through for the DHCPv4 module to process,
regardless of the destination IP address.

int64_t print_interval = sys_clock_timeout_end_calc(K_SECONDS(1));
/* Print log every seconds */
int64_t print_info = print_interval - k_uptime_ticks();
if (print_info <= 0) {
[...]
}
The above condition will simply never be true.
Then there is lots of back-and-forth time conversions using expensive
base-10 divisions for each loop iterations which is likely to impact
performance.
Let's do the time conversion only once outside the loop and track
everything in terms of ticks within the loop. Also the various timeouts
are open-coded based on the absolute uptime tick so to sample it only
once per round. Using sys_timepoint_calc() and sys_timepoint_timeout()
would have introduced additional uptime tick sampling which implies the
overhead of a downstream lock each time for no gain. For those reasons,
open coding those timeouts bears more benefits in this particular case
compared to using the timepoint API.
Then this:
secs = k_ticks_to_ms_ceil32(loop_time) / 1000U;
usecs = k_ticks_to_us_ceil32(loop_time) - secs * USEC_PER_SEC;
The above should round down not up to work accurately. And the usecs
value will become garbage past 1.2 hour of runtime due to overflows.
And no need to clamp the wait period which is on the microsec scale
using the total duration argument being on the millisec scale. That's
yet more loop overhead that can be omitted. The actual duration is
recorded at the end anyway.

This is meant as a substitute for sys_clock_timeout_end_calc()
Current sys_clock_timeout_end_calc() usage opens up many bug
possibilities due to the actual timeout evaluation's open-coded nature.
Issue ##50611 is one example.
- Some users store the returned value in a signed variable, others in
an unsigned one, making the comparison with UINT64_MAX (corresponding
to K_FOREVER) wrong in the signed case.
- Some users compute the difference and store that in a signed variable
to compare against 0 which still doesn't work with K_FOREVER. And when
this difference is used as a timeout argument then the K_FOREVER
nature of the timeout is lost.
- Some users complexify their code by special-casing K_NO_WAIT and
K_FOREVER inline which is bad for both code readability and binary
size.
Let's introduce a better abstraction to deal with absolute timepoints
with an opaque type to be used with a well-defined API.
The word "timeout" was avoided in the naming on purpose as the timeout
namespace is quite crowded already and it is preferable to make a
distinction between relative time periods (timeouts) and absolute time
values (timepoints).
A few stacks are also adjusted as they were too tight on X86.

Associate command handler did not validate the provided address length.
In result, if provided address string was longer than the expected

This change introduces test coverage for association request and
response. Based on this coverage, several closely related issues were
found in the association process which cannot be split into separate
changes without breaking the build.
Most notably did the associate and disassociate net_mgmt commands send
already encoded IEEE 802.15.4 MPDUs to L3 rather than L2. L3 treated
them as payload and made L2 wrap them with another LL header/footer
which produced invalid packets.
The tests also enforce better aligment of the association process with
the IEEE 802.15.4-2020 standard:
* Association requests now ask for ACK as required by the standard. The
fake driver was enhanced to produce ACK packages when requested.
* macPanId and macCoordinator* MAC PIB attributes are set in the right
order for improved filtering of association responses.
* The coordinator may decide not to assign a short address to the end
device even when associated. This is now supported.
* The coordinator may or may not use a short address. Coordinators
choosing not to support short addresses are now supported.
* Updating the association will now remove any previously added short
address from the hardware filter.
* The short address may no longer be changed by the user while
associated to a PAN. Only the coordinator is allowed to allocate short
addresses.
* Validation of outgoing and incoming association request/response
packets is improved.
All changes are documented by pointers into the spec.

Both addresses will have the same solicited-node multicast address

If the address was removed immediately after being added (e.g. because the
interface MAC address is changed on boot), it would remain in the DAD timer

In one scenario, the DAD timeout would eventually fire, causing the
now-removed address to be modified, potentially causing issues that way.
In another scenario, if the interface was immediately brought back up
again with a different link-local address, this new address would reuse the
first address slot on the interface. Starting the DAD process for this new
address would lead to the same address slot being added to the DAD timer
list a second time, causing an infinite list and associated lockup during

The method ieee802154_radio_handle_ack() does not belong to the
PHY/radio layer but to the L2 layer. It is a callback called from the
radio layer into the L2 layer and to be implemented by all L2 stacks.
This is the same pattern as is used for ieee802154_init(). The
'_radio_' infix in this function is therefore confusing and
conceptually wrong.
This change fixes the naming inconsistency and extensively documents
its rationale.
It is assumed that the change can be made without prior deprecation of the
existing method as in the rare cases where users have implemented custom
radio drivers these will break in obvious ways and can easily be fixed.
Nevertheless such a rename would not be justified on its own if it were
not for an important conceptual reason:
The renamed function represents a generic "inversion-of-control" pattern
which will become important in the TSCH context: It allows for clean
separation of concerns between the PHY/radio driver layer and the
MAC/L2 layer even in situations where the radio driver needs to be
involved for performance or deterministic timing reasons. This
"inversion-of-control" pattern can be applied to negotiate timing
sensitive reception and transmission windows, it let's the L2 layer
deterministically timestamp information elements just-in-time with
internal radio timer counter values, etc.

- According to the standard a CSMA/CA failure should lead to immediate

retransmissions have been configured.
- The number of retransmissions was off by one. It is now used as

dBm) and lets 255 represent an "unknown RSSI" (IEEE 802.15.4-2020,
section 6.16.2.8). On the TX path the rssi attribute will always be
zero. Out-of-range values will be truncated to max/min values.
The change also introduces conversion functions to and from signed dBm
values and introduces these consistently to all existing call sites. The
"unknown RSSI" value is represented as INT16_MIN in this case.
In some cases drivers had to be changed to calculate dBm values from
internal hardware specific representations.
The conversion functions are fully covered by unit tests.

Compiling an application with CONFIG_NET_ZPERF=y leaving
CONFIG_ZPERF_WORK_Q_THREAD_PRIORITY at its default value would
systematically cause a kernel panic during thread initialization.
The Kconfig variable is NUM_PREEMPT_PRIORITIES by default. Application
threads may not define a priority lower than NUM_PREEMPT_PRIORITIES - 1,
though.
This change limits zperf's thread priority to a valid range. It does not
change the default value as it makes sense to default the thread
priority to the lowest possible value (which is NUM_PREEMPT_PRIORITIES)
but Kconfig does not allow for arithmentic. So the combination of
CLAMP() plus the Kconfig default will ensure min priority plus limit the
range to valid values no matter what has been defined as priority in
Kconfig.

In previous patch fixing this issue, I've missed the fact that offloaded
drivers would not set the context->local address, which resulted in a
regression, where the previously introduced assert would hit in
offloaded cases. Not setting laddr is not a problem in case of
offloading, as it's only used in net_tcp_connect() which would not be
reached in this case.
Therefore I propose to remove previous patch to get rid of regression.
As an alternative fix, verify the laddr just before use, so that it is
only checked when native net stack is in use.

Coverity reported, that laddr pointer used in net_context_connect()
could be passed as NULL to net_tcp_connect() where it could be
dereferenced. This is because the actual setting of laddr to a valid
address structure was only done after
net_sin/sin6_ptr(&context->local)->sin/sin6_addr verification.
In practice though, the aforementioned pointer verification would always
pass, as the bind_default() guarantee that the context->local address is
set to an unspecified address (if it hasn't been set earlier).
Therefore refactor the code a bit: replace the pointer verification
with NET_ASSERT - only to assure that we can catch regression in case
for any reason the behavior of bind_default() changes. This should also
ensure that Coverity no longer reports that laddr is NULL when reaching
net_tcp_connect().

In case TCP connection is being closed from the TCP stack, due to for
instance retransmission timeout, the stack should also switch the TCP
state to CLOSED. Otherwise, there was a risk of dereferencing the TCP
context twice, for example if the application was in active socket
send(), and tried to reschedule data transmission.
Additionally, make sure that the TCP_CLOSED state handling is a no-op
state - otherwise, there is a risk that if packets keep incoming before
the application dereferences the TCP context on its side, TCP stack
will incorrectly dereference the context for the second time from
within due to current TCP_CLOSED state logic.

In order to support external IP stacks that might have Connection
ID support, the LwM2M engine should allow client to bypass default
behaviour.
New set_socketoptions() callback added into client context
that allows overriding all socket opetions. This is called
after a socket is opened, but before the connect() is
called. This cannot be combined with load_credentials() callback
on all platforms as for example nRF91 requires modem offline
when credentials are written. This would cause socket to be closed
as well.
Second change is that we allow fine tuning of what we do with
socket handle when QUEUE mode is enabled and engine enters idle
state.
First option would be to close the socket. That would cause
TLS Alert(Close Notify) to be send. This is a band choice if
LTE modem was already in PSM or eDRX power saving mode.
Second option would be to delay socket closing until we
are going to send LwM2M update. There TLS Alert is also send,
but most probably lost due to NAT mapping timed out. This
is a best choice for LTE modem with DTL session cache enabled.
Two new options are to keep socket open, and either stop listening
or just keep listening. Both of these options work fine when
we have DTLS Connection ID support.

In case lwm2m_socket_start() internal error, it should only do cleanup
on the socket, i. e. call lwm2m_socket_close(), not lwm2m_engine_stop().
The latter resets the entire lwm2m_context, which results in removal of
active observations.
This should not be done, as it collides with the RD client logic, where
connection resumption may skip the full registration phase, in result
not notifying the server that it should restart the observations.
At the same time, the RD client should clean the lwm2m_context when it's
done trying to update the registration and proceeds with regular
registration/bootstrap in the network error handler. In that case, only
the socket was closed, so the lwm2m_context needs to be reset
separately.

The IEEE 802.15.4 standard does not specify a "Sub-GHz" option.
Therefore this option will be deprecated in the foreseeable future.
Rationale: Selecting PHYs and frequency bands is abstracted by the
concept of channel pages (see IEEE 802.15.4-2020, 10.1.3).
Radio drivers may expose additional configuration options that
specify the low level frequency band, operating mode and other
PHY-specific parameters. Such parameters should be exposed on a driver
instance level, e.g. via devicetree or as runtime options of the driver.
PHY-specific attributes derived from driver settings (e.g. available
channels) can then be announced to L2 w/o the user having to be aware of
any implementation details of the specific PHY.
Future changes will introduce the necessary infrastructure to define
channel pages and other PHY-specific configuration options to
replace this option. New drivers should therefore not rely on this
option.

In order to allow the TLS accept() call to be interrupted, it should

The accept() so far would block with mutex held, making it impossible to
interrupt it from another thread when the socket was closed.
Fix this, by reusing the condvar mechanism used for receiving. It's OK
to use the same routine, as underneath accept() is monitoring the same
FIFO as recv().
Additionally, simplify k_fifo_get() handling in accept() - as the
waiting now takes place on condvar, it can be used in a non-blocking
manner. Blocking accept() call should not reach this place if there's no
new incoming connection waiting on the FIFO.

Installing recv callback with net_context_recv() after
net_context_connect() left an opening for a possible race - in case the
server send some data immediately after establishing TCP connection, and
Zephyr did not manage to install the callback on time, the data would be
lost, corrupting the stream.
This can be avoided, by installing the recv callback before the
connection is triggered. As net_context_recv() called w/o timeout only
registers the callback function, it should have no negative impact. The
only change on the TCP side is when the connection is closed - in case
TCP is in connect stage, do not call the recv callback (before this
change it'd be NULL at that point).

receive frames with security level 4 shall discard them, as
described in 9.2.4. The counter mode encryption and cipher
block chaining message authentication code (CCM) used allows

Over time, some non-standard concepts and extensions were introduced
into the stack (in KConfig, in drivers, in the internal API and into the
implementation) which makes introduction of additional standard-
compliant extensions like TSCH (and others) unnecessarily difficult.
To introduce extensions like TSCH it is required for the IEEE 802.15.4
stack to become more structurally aligned with the standard again which
will be the focus of some of the upcoming preparatory changes.
One way to check and prove standard compliance is to reference the
standard from within the source code. This change therefore introduces
inline references to the IEEE 802.15.4-2020 standard wherever possible.
Deviations from the standard are documented with TODO or deprecation
labels to be addressed in future changes.
In the future, new code introduced to the IEEE 802.15.4 stack should
be documented and reviewed for standard-compliance to avoid further
divergence. Most importantly:
* MAC/PHY configuration (via net mgmt, radio API, devicetree or
KConfig) should always be directly linked to well-defined MAC/PHY
PIB attributes if visible to the MAC API or the end user.
* Net management/shell/radio API commands should have a documented
reference to the corresponding MLME action from the standard.

The current implicit MAC payload length algorithm (based on

This change produces standard-conforming MAC payload length
values and simplifies access to payload length.
It would have been possible to fix the current footer pointer
based approach but there are arguments in favor of the new
approach:
- The footer pointer is used nowhere in the current code
base and makes length calculations rather non-obvious.
- The new approach does not use more memory and is easier
to understand and use.
- This change is a first step to support of IEEE 802.15.4
information element (IE) support. At a later stage the
distinction between MAC payload length and frame payload
length will be introduced and become relevant to
distinguish between header and payload IEs. At that point

Instead of having a single global mutex, covering, in most cases

data, use local mutex protection instead. The global mutex remains only
to protect access to shared resources (IPv4/6 context pool, timer lists
etc.).
Finally, rework the timer expiry handlers, to prevent interface
functions from being called while the global lock is held (the global
mutex has to be held when iterating over the timer list, as lists are
not thread safe). The reason for this is to avoid possible deadlock
scenario. The global mutex is sometimes being locked, while inside

OpenThread networks do not use ND or MLD as they have their own set of
protocols to cover this functionality. So far, the use of OpenThread
with Zephyr relied on disabling those protocols support statically with
Kconfig, which prevented OT interfaces from being used along with other
IPv6 interfaces.
With the new network interface flags, it's now possible to disable ND
and MLD on individual interfaces, therefore disable them for OT
specifically.

The init infrastructure, found in `init.h`, is currently used by:
- `SYS_INIT`: to call functions before `main`
- `DEVICE_*`: to initialize devices
They are all sorted according to an initialization level + a priority.
`SYS_INIT` calls are really orthogonal to devices, however, the required
function signature requires a `const struct device *dev` as a first
argument. The only reason for that is because the same init machinery is
used by devices, so we have something like:
```c
struct init_entry {
int (*init)(const struct device *dev);
/* only set by DEVICE_*, otherwise NULL */
const struct device *dev;
}
```
As a result, we end up with such weird/ugly pattern:
```c
static int my_init(const struct device *dev)
{
/* always NULL! add ARG_UNUSED to avoid compiler warning */
ARG_UNUSED(dev);
...
}
```
This is really a result of poor internals isolation. This patch proposes
a to make init entries more flexible so that they can accept sytem
initialization calls like this:
```c
static int my_init(void)
{
...
}
```
This is achieved using a union:
```c
union init_function {
/* for SYS_INIT, used when init_entry.dev == NULL */
int (*sys)(void);
/* for DEVICE*, used when init_entry.dev != NULL */
int (*dev)(const struct device *dev);
};
struct init_entry {
/* stores init function (either for SYS_INIT or DEVICE*)
union init_function init_fn;
/* stores device pointer for DEVICE*, NULL for SYS_INIT. Allows
* to know which union entry to call.
*/
const struct device *dev;
}
```
This solution **does not increase ROM usage**, and allows to offer clean
public APIs for both SYS_INIT and DEVICE*. Note that however, init
machinery keeps a coupling with devices.
**NOTE**: This is a breaking change! All `SYS_INIT` functions will need
to be converted to the new signature. See the script offered in the
following commit.

SO_RCVBUF option processing at the TCP level was broken. The option

chance to have custom value. If the user modified the option after the

This commit fixes this, by checking the option value whenever new packet
is processed, so that the configured window size is updated at the TCP
level before we report it in the TCP ACK. In order to achieve this,
introduce a new helper function, to refresh the configured window sizes,
to avoid bloating `tcp_in()` even further.

Provide a means of declaring zero or more HTTP services, each

Static HTTP resources are those which have fixed paths[1] which
are known prior to system initialization. Some examples of
static http resources would be
* a forwarder from '/' to '/index.html'
* a REST endpoint with fixed path '/api/foo' and detail
pointing at some implementation-specific function
* a Javascript file in string form with fixed path '/js/util.js'
* a 'construction' image with path '/res/work.png'
* a gzip-compressed 'Hello' HTML file at '/hello.html'
Without describing in any detail how static HTTP resources are
organized or served by any given HTTP server, we can describe
what static resources exist on a system in a common way that
does not require any optional facilities (e.g. filesystem) and
relies only on addressable memory.
Additionally, for the purposes of simply allowing others
to implement custom HTTP servers in a consistent way, or
benchmarking implementations, or having a consistent testsuite
to use across multiple implementations, it is helpful to have
a common method to declare HTTP services and static resources
for Zephyr.

TCP implementation abused the packet processing result reporting
mechanism, by reporting NET_DROP for every packet other than data
packets (which were passed to the application). This simplified the TCP
implementation a bit, as it didn't need to deal with packet releasing.
While technically it worked, it gave incorrect results when it comes to
packet statistics, as a lot of valid TCP packets were counted as
dropped.
This commit fixes this. Each packet that was properly processed by the
TCP stack is not either released at the TCP level, or passed to the

In the case of no ARP entry, the incoming packet is added to the ARP's
pending queue, while ARP is being resolved. Here a reference is taken
by the ARP layer to the packet to avoid it being freed, but the Ethernet
immediately puts down the reference and send the ARP packet to the
driver.
If the ARP request fails for some reason, L2 returns failure to net_if
which then puts down the reference and the packet will be freed as the
reference count is now zero.
But the packet is still in the ARP's pending queue and after timeout
ARP will put down the reference causing double free bus fault (double
free message is only seen if the CONFIG_NET_PKT_LOG_LEVEL_DBG is

According to RFC3927, hosts with only IPv4 LL address should still be
able to send packets to destination w/o IPv4 LL address:
A host with an IPv4 Link-Local address may send to a destination
which does not have an IPv4 Link-Local address. If the host is not
multi-homed, the procedure is simple and unambiguous: Using ARP and
forwarding directly to on-link destinations is the default route
This behaviour however was not possible with Zephyr, which only allowed
to use IPv4 LL source address for IPv4 LL destinations.
Fix this, by introducing a final fallback (only if IPv4 autoconf is
enabled), to select IPv4 LL address as a source address if no other
address is available.
Additionally, modify the ARP routine a bit if IPv4 LL address is in use.
There's no really point to forward the packet to gateway if IPv4 LL
address is used, as such addresses are not routable. Instead, try to
find the peer in local network in such case.

IEEE802154 drivers expect, that a complete 802.15.4 frame fits into a
single net_buf provided in a net_pkt.
There is a corner case with header compression when this could not be
the case. If the IPv6 packet before IPHC exceeded 802.15.4 MTU, it'd
consist of several net_buf's. This was not an issue, if the IPv6 packet
after header compression still required fragmentation, as the
fragmentation module took care of formatting individual net_buf's
properly.
For short range of packet sizes however this was no the case. The IPv6
packet, after header compression, might not require fragmentation any
more. As the IPHC logic only modified the IPv6 header part, by trimming
the buffer in front of the net_buf, such a packet would still consist of
two net_bufs, even though it should fit into a single 15.4 frame. Such
packet was passed to the driver, causing the driver to send only part of
the packet, from the first net_buf.
Fix this, by using net_pkt functions to manipulate the packet, instead
of operating on net_buf directly. net_pkt_pull() will not trim the
buffer in front, but rather move the entire packet content to the front.
On the other hand, net_pkt_compact() will assure that there's no gaps in
the net_bufs. In result, packets that do not require fragmentation,
should be placed into a single net_buf, as expected by drivers.

Currently, if timeout is not configured for the network initialization in
the config module, the initialization function will configure IPv4/IPv6/
DHCPv4 regardless of the interface status. This is not the case when the
timeout is set, and the interface was not brought up during the timeout
period. This lead to ambiguity in terms of interface initialization.
This commits unifies the behaviour between these two cases. The
aforementioned initializations will always take place, regardless of the
interface status. The IPv4/IPv6 and DHCPv4 routines should be prepared
to deal with interfaces that are not brought up. The only difference
now, between timeout and no timeout scenario, is that the former will
report an error in case the timeout occurs wile waiting for the expected
events.

The net_context/TCP connection context ref counting needed to be fixed,
to avoid situation where TCP connection context could be released
before net_context is released.
Generally, this commit modifies the ref counting of the above as
follows:
* net_context is referenced both by the application and TCP stack, when
created.
* TCP context is referenced by the application when created. The TCP
stack adds ref to the TCP context only after connection has been
established.
* TCP stack needs to call the final upper layer callback when connection
is closed, but before the TCP context is released (i. e. to give upper
layer chance to dereference the context on its side). For this,
tcp_conn_close() was introduced which is called from within TCP stack
instead of directly dereferencing the TCP context.
* TCP stack dereferences the net_context only after the TCP context has
been released (i. e. upper layer has dereferenced TCP context on it's
side and connection has been tear down, if established).

This is just a regulatory hint to the chipset, there could be other
regulatory hints e.g., beacon that can override this configuration, so,
an additional option to force this setting despite other hints is also
given for testing purposes.

This patch reworks how fragments are handled in the net_buf
infrastructure.
In particular, it removes the union around the node and frags members in
the main net_buf structure. This is done so that both can be used at the
same time, at a cost of 4 bytes per net_buf instance.
This implies that the layout of net_buf instances changes whenever being
inserted into a queue (fifo or lifo) or a linked list (slist).
Until now, this is what happened when enqueueing a net_buf with frags in
a queue or linked list:
1.1 Before enqueueing:
+--------+ +--------+ +--------+
|#1 node|\ |#2 node|\ |#3 node|\
| | \ | | \ | | \
| frags |------| frags |------| frags |------NULL
+--------+ +--------+ +--------+
net_buf #1 has 2 fragments, net_bufs #2 and #3. Both the node and frags
pointers (they are the same, since they are unioned) point to the next
fragment.
1.2 After enqueueing:
+--------+ +--------+ +--------+ +--------+ +--------+
|q/slist |------|#1 node|------|#2 node|------|#3 node|------|q/slist |
|node | | *flag | / | *flag | / | | / |node |
| | | frags |/ | frags |/ | frags |/ | |
+--------+ +--------+ +--------+ +--------+ +--------+
When enqueing a net_buf (in this case #1) that contains fragments, the
current net_buf implementation actually enqueues all the fragments (in
this case #2 and #3) as actual queue/slist items, since node and frags
are one and the same in memory. This makes the enqueuing operation
expensive and it makes it impossible to atomically dequeue. The `*flag`
notation here means that the `flags` member has been set to
`NET_BUF_FRAGS` in order to be able to reconstruct the frags pointers
when dequeuing.
After this patch, the layout changes considerably:
2.1 Before enqueueing:
+--------+ +--------+ +--------+
|#1 node|--NULL |#2 node|--NULL |#3 node|--NULL
| | | | | |
| frags |-------| frags |-------| frags |------NULL
+--------+ +--------+ +--------+
This is very similar to 1.1, except that now node and frags are
different pointers, so node is just set to NULL.
2.2 After enqueueing:
+--------+ +--------+ +--------+
|q/slist |-------|#1 node|-------|q/slist |
|node | | | |node |
| | | frags | | |
+--------+ +--------+ +--------+
| +--------+ +--------+
| |#2 node|--NULL |#3 node|--NULL
| | | | |
+------------| frags |-------| frags |------NULL
+--------+ +--------+
When enqueuing net_buf #1, now we only enqueue that very item, instead
of enqueing the frags as well, since now node and frags are separate
pointers. This simplifies the operation and makes it atomic.

interface to transmit data (for example cable plugged in).
* Introduce a new interface flag: NET_IF_DORMANT, along with
corresponding helper functions. The flag should be set on an
iterface when the interface is not ready to transmit application data,
for example still not joined a Wi-Fi network.
* Introduce a new interface flag: NET_IF_RUNNING, indicating that
interface is ready to transmit application data.
* Update the meaning of the NET_IF_UP flag - it now singnalizes whether
an interface has been brought up/down by the application (admin
up/down).
* Introduce operational state of an interface, derived from above. It
reflects the internal interface state.

This change implements part two of the program laid out in the TSCH RFC,
see #50336#issuecomment-1250250154 :
> Consolidate IEEE 802.15.4 options in net_pkt
This change improves decoupling of generic net core code from
IEEE 802.15.4 internals. It also simplifies IEEE 802.15.4
attribute cloning and thereby makes it easier to maintain and less
error prone (and probably even faster as individual bits are no longer
copied over separately).
This enables us to extend and design IEEE 802.15.4 L2 attributes inside
the package in isolation from the net core code which will no longer
have to be changed when introducing changes or additions to the flags.
This flexibility will be built upon in later change sets to model the
IEEE 802.15.4 attributes closer to the spec.
The solution is inspired by Linux's sk_buff->cb attribute which addresses
the same concern as the attribute introduced in this change set:
https://elixir.bootlin.com/linux/v6.0.1/source/include/linux/skbuff.h#L871
As the inline comment says: The cb attribute can be made a union or even a
uint8[something] in the future, if further L2s need a control block, too.
Right now such full indirection would make the code overly abstract, so
I chose to compromise with maintainability in mind.
Care has been taken to ensure that this changes does not introduce
additional padding into the net package. To maintain zero-padding, future
changes to the net packet struct will have to ensure that the
IEEE 802.15.4 struct is 4-byte aligned (iff the IEEE 802.15.4 struct
continues with max uint32_t scalar members) which is no deviation from
the previous implementation.

The IEEE 802.15.4 L2 now sets the ll protocol in the packet to a
specific value. This corresponds to the respective solution in Linux and
is required to validate access to IEEE 802.15.4 specific attributes of
the packet.
Later change sets will rely on this value to ensure that IEEE 802.15.4
specific package content can only be accessed on IEEE 802.15.4 packages.
Signed-off-by: Florian Grandel <jerico.dev@gmail.com>
The net packet structure contains pointers to link-layer source and
destination addresses. Usually, these structures do not point to
separately allocated memory but directly into the packet's data buffer.
In case of a deep package clone (which includes copying the buffer) the
copy of the ll addresses continued to point into the old package
(contrary to a rather misleading inline comment). This was proven by an
additional failing unit test assertion.
As the original package may be unreferenced while the cloned package is
still being accessed, the ll address pointers of the cloned package may
become invalid.
The fix consists of two parts:
* First it is determined whether a given ll address actually points into
the buffer and if so at which logical cursor offset it is located.
* If the address points into the package buffer then the cursor API is
used to determine the corresponding physical memory location in the
cloned package. The ll address of the cloned package is then patched
to point to the cloned buffer.
Additional assertions were introduced to the existing unit test to ensure
that the newly generated address points to the correct content of the
cloned package.
The solution is implemented in a generic way so that the previously
redundant implementations were consolidated into a single one. The code
includes a check that ensures that the ll address check and manipulation
will be skipped in case of shallow package copies.
The change also addresses problems related to the "overwrite" flag of the
package:
* Package cloning assumes the overwrite flag to be set. Otherwise it
will not work correctly. This was not ensured inside the clone method.
* Package cloning manipulates the overwrite flag of the cloned package
but does not reset it to represent the same state as the original
package.
The change introduces a fix and unit test assertions for both problems.

Most IEEE 802.15.4 drivers do not support promiscuous mode, some do.
There is a dedicated L2 flag to signal this capability to clients.
Unfortunately the IEEE 802.15.4 L2 stack does not announce this flag
even for drivers that correctly expose it in their HW capabilities.
Some clients (notably the OpenThread L2) even uses promiscuous mode
without checking whether the driver actually supports it.
This change lets the vanilla IEEE 802.15.4 L2 check the driver's
HW capabilities to announce promiscuous mode on its 'get_flags()'
interface if supported.
The OpenThread L2 uses a constant (potentially incorrect) response
to 'get_flags()'. Fixing the OpenThread L2 is out of scope of this
change. This change just introduces TODO messages to the OpenThread code
so that the OpenThread team may fix the issue (or delete the TODO if they
deem it irrelevant).

The bridge subsystem was written with a ETH_BRIDGE_INITIALIZER that
assumed it could initialize a k_mutex with a zero-filled initializer.
That never worked. Unlike semaphores, mutexes have always required a
runtime call to k_mutex_init(). What happened instead is that
k_mutex_un/lock() returned error codes, which were ignored by the code
here. So no locking was happening.
This was discovered while migrating to zync, where an attempt to
unlock an unlocked mutex is a panic condition (and where zero-filled
initializers are legal, but represent an unfair semaphore and not a
mutex, so deadlock correctly).

IEEE 802.15.4 short address support is incomplete in several places.
This change improves short address support without claiming to fix
it everywhere. Future iterations will have to continue where this change
leaves off.
The purpose of this change was to:
* use the short address returned by association responses,
* automatically bind IEEE 802.15.4 datagram sockets to the short
address if available,
* use the short address in outgoing packages where applicable,
* improve validation of association/disassociation frames,
* model association more closely to the spec by tying it to the
existence of a short address in the MAC PIB thereby removing
redundancy in the PIB (which makes race conditions less probable),
* keep both, the short and extended addresses, of the coordinator.

This is a preparatory change that fixes one aspect of short address
handling before fixing endianness so that the endianness fix can be
applied consistently in this method.

The IEEE 802.15.4 L2 code stores representation of attributes like
PAN id, short address and extended address in different encodings:
* big endian for extended address and CPU byte order for everything
else whenever such attributes enter user space (except for IP/socket
link layer addresses which are always big endian - even in case of
short addresses - to maintain POSIX compatibility).
* little endian for everything that is close to the radio driver as
IEEE 802.15.4 frames are little endian encoded.
Endianness was almost nowhere documented which led to several bugs and
inconsistencies where assignments of different byte order were not
converted (or sometimes converted, sometimes not).
This change documents endianness wherever possible within the realm of
the IEEE 802.15.4 L2 code. Conversion bugs and inconsistencies that were
revealed by the improved documentation will be fixed in a separate
commit.

If a L2 link has been established, then the DHCP is taking too long as
it has to go through its capped exponential backoff timers to trigger
discover (The DHCP starts immediately during init, this is itself wrong,
it should start on a link UP notification) that delays the DHCP for
few seconds to a minute.
And if we do stop and start DHCP then also it goes through the initial
delays (though configurable), which is also not ideal.
Add support for restarting DHCP without any delay, i.e., release and
send discover immediately.
This is also useful in case L2 switches to a different subnet, in this
case Zephyr doesn't restart DHCP automatically, this API can be used by
L2 apps/drivers to restart DHCP to get new subnet IP.

The net_core:process_data() and connection:net_conn_input() methods are
the central network packet reception pipeline which:
1) guide network packets through all network layers,
2) decode, validate and filter packages along the way and
3) distribute packages to connections/sockets on all layers.
This code seems to have grown complex and rather cluttered over time as
all protocols, layers and socket implementations meet there in one single
place.
The code also reveals its origin as a pure IP stack which makes it hard
to introduce non-IP protocols and their supporting socket infrastructure
in a modularized way.
For an outside contributor it seems almost impossible to add another
protocol, protocol layer, filter rule or socket implementation without
breaking things.
This change doesn't try to solve all issues at once. It focuses
exclusively on aspects that maintain backwards compatibility:
* Improve modularization and encapsulation on implementation level by
disentangling code that mixes up layers, protocols and socket
implementations.
* Make IP just one protocol among others by removing assymmetry in
protocol handling logic and introduce preprocessor markup so that
IP-specific code can be eliminated by the preprocessor if not needed.
* Use preprocessor markup to delineate hook points for future
modularization or expansion without introducing structural changes (as
this would almost certainly break the API).
* Reduce cyclomatic complexity, use positive rather than negative logic,
improve variable naming, replace if/elseif/else blocks with switches,
reduce variable span, introduce inline comments where code does not
speak for itself, etc. as much as possible to make the code overall
more human-friendly.
Background: These are preparative steps for the introduction of IEEE
802.15.RAW sockets, DGRAM sockets and sockets bound to PAN IDs and device
addresses similar to what the Linux kernel does.

As of today <zephyr/zephyr.h> is 100% equivalent to <zephyr/kernel.h>.
This patch proposes to then include <zephyr/kernel.h> instead of
<zephyr/zephyr.h> since it is more clear that you are including the
Kernel APIs and (probably) nothing else. <zephyr/zephyr.h> sounds like a
catch-all header that may be confusing. Most applications need to
include a bunch of other things to compile, e.g. driver headers or
subsystem headers like BT, logging, etc.
The idea of a catch-all header in Zephyr is probably not feasible
anyway. Reason is that Zephyr is not a library, like it could be for
example `libpython`. Zephyr provides many utilities nowadays: a kernel,
drivers, subsystems, etc and things will likely grow. A catch-all header
would be massive, difficult to keep up-to-date. It is also likely that
an application will only build a small subset. Note that subsystem-level
headers may use a catch-all approach to make things easier, though.
NOTE: This patch is **NOT** removing the header, just removing its usage
in-tree. I'd advocate for its deprecation (add a #warning on it), but I
understand many people will have concerns.

The IEEE 802.15.4 security implementation had several severe bugs:
* A regression introduced by 6ea225e34a
(net/ieee802154: Finally removing usage of ll_reserve in L2)
introduced a buffer leak (reading/ writing beyond the end of the frame
buffer) and led the security implementation to malfunction in all but
the simplest cases (i.e. encryption/authentication: none).
* Encryption vs. authentication modes were not properly implemented i.e.
encryption was always active even if not required by the chosen
encryption level.
* Nonce endianness was not correctly handled on decryption of packets
which led to authentication failures.
* The frame counter was not checked for overflows.
* The encryption output buffer limit (out_buf_max) was not correctly set.
* Setting an invalid key mode led to a NULL pointer deref.
* We use CCM rather than CCM* as crypto.h does not provide access to
CCM*. CCM does not support encryption-only operation, though. This
condition was not checked by the code.
